Test Drive: 2014 BMW 428i Convertible

BMW 428i Cabrio 2014_test drive_01Convertible always looks at its best with the roof down. This new BMW 4 Series Convertible however, looks elegant also when the roof is closed thanks to the sleek design of its three-piece retractable hardtop.

With a push of a button, the coupe turns into convertible in 20 seconds. The windblock is now smaller, lighter and easier to use, plus it is more effective than previous variants. Available as an option for the first time, the standard seats and the optional sport seats can be equipped with neck warmers for the driver and front passenger. New neck warmers make the convertible more enjoyable to drive with the roof down even when the weather is not that hot anymore.

Compared to the coupe, usually the only negative thing with the convertible is the higher noise level, because the softop or even a hardtop doesn’t provide as good soundproofing as a coupe’s roof. The hardtop of the new BMW 4 Series Convertible features a number of design improvements that reduce noise levels to provide much quieter and enjoyable interior ambience. The interior roof is fully lined and features also lamps to give the feeling of the premium sport coupe.

The sound-absorbing headliner reduces wind noise by up to 2 dB in comparison to the predecessor model. The low seats ensure more headroom for the passengers, and there is also more rear legroom compared to the predecessor. The seats are electrically adjustable as standard in the 4 Series Convertible.

In addition to the standard model, the new Convertible is available with three equipment lines; Sport Line, Modern Line and Luxury Line. The sportiest choice is the M Sport Package. It comes with the aerodynamic package including body components such as the front apron with large air intake and the rear bumper with diffuser. The interior is upgraded with exclusive sports seats with M piping and royal blue contrast stitching, M door sill finishers, M leather steering wheel and M driver’s footrest.

The package also includes the M Sport suspension with a firmer spring/damper set-up and stiffer anti-roll bars. The M Sport suspension, which can also be ordered separately, provides sportier driving experience, but doesn’t make the car uncomfortable for low speed cruising.

This BMW 428i is powered by a 2.0-litre four-cylinder turbocharged petrol engine. It provides maximum output of 180 kW (245 hp) at 5,000 – 6,500 rpm and peak torque of 350 Nm at 1,250 – 4,800 rpm. The engine can be paired with the six-speed manual gearbox or eight-speed automatic transmission. You can even choose to have this car with the BMW xDrive four-wheel drive system.

The acceleration from standstill to 100 km/h with the 428i takes 6.4 seconds. If you want even better performance, there is also the 435i with the 3.0-litre engine delivering 225 kW (306 hp). If you drive most of the time with the roof down, even the 420i might be enough with its 135 kW (184 hp) engine. However, equipped with the M Sport package, the sporty looks of the 4 Series Convertible deserve a powerful engine.
